For influenza experts, the question is not whether the world is going to have a new flu pandemic, but when

This isn't easy to communicate to the public. Bird flu and the potential for a human flu pandemic have been making headlines in recent weeks, but the subject presents more uncertainties than certainties.

New way to fight antibiotic-resistant Staphylococcus infections

Researchers at the University of California, San Diego School of Medicine and Children’s Hospital and Health Center, San Diego have discovered that "Staph" bacteria use a protective golden armor to ward off the immune system, a finding with the potential to lead to new treatments for serious infections now increasingly resistant to standard antibiotics.

Ducks possibly the culprit in spreading bird flu

An international team, which included experts from China, Indonesia, Thailand, the US and Vietnam, say that domestic ducks possibly pose a major threat of spreading avian flu to animals and humans, as not only do they carry the virus with few visible signs, the virus is able to mutate in them, which means they could trigger a human pandemic.

Gene defect linked to heart disease

Researchers at the University of Texas Southwestern Medical Center in Dallas, have found by studying DNA from 11 members of one family, who suffered from aortic heart disease, a genetic mutation that causes a common birth defect and contributes to heart disease in adults.

Studies explore genetic interactions between two well-known tumor suppressor proteins, PTEN and TSC2

Two papers in the August 1 issue of Genes & Development explore the genetic interactions between two well-known tumor suppressor proteins, PTEN and TSC2.

New theory on aging says popping pills and drinking orange juice no guarantee you'll live longer

In direct contrast to previous reports, researchers now say that drinking gallons of orange juice and popping vitamin pills may not be a guarantee that you will live longer.

Chemical sealant - poloxamer 188 can repair damage to cardiac muscle cell membrane

A common chemical used in the manufacturing and pharmaceutical industries can repair damage to cardiac muscle cell membranes and prevent heart failure in mice with the genetic mutation that causes Duchenne muscular dystrophy, according to scientists at the University of Michigan Medical School.

Study shows mutation in NOTCH1 gene causes aortic valve disease

By studying five generations of a Dallas family, UT Southwestern Medical Center researchers have discovered that a mutation in a key gene causes aortic valve disease, a common heart birth defect as well as a major contributor to adult heart disease.

New molecular insights may one day lead to opportunities to stave off old age

Delving deep into the molecular subtleties of a strain of mice engineered to age rapidly, scientists have found that an accumulation of genetic mutations prompts a cascade of programmed cell death that seems to underpin the aging process.

Extraordinary number of genes are required for prenatal mammalian development

A team of scientists led by Cornell University's Dr. John Schimenti reports today that an extraordinary number of genes are required for prenatal mammalian development. The researchers estimate that up to 19% of all genes are vital for embryogenesis in mice.

Individuals with inactive heterozygous ALDH2, a tendency to alcohol flushing have a greater susceptibility to hangovers

Alcohol consumption is an integral part of the Japanese business culture. Hangovers, however, can have substantial economic drawbacks.

Data directly support a pathogenetic model of acute leukemia

Acute myeloid leukemia (AML) is frequently caused by genetic alterations that affect transcription factors, such as AML1-ETO and mutations affecting genes involved in signal transduction pathways, such as FLT3.

Having asthma, hay fever or another allergic condition may reduce the risk of developing Glioblastoma multiforme

Glioblastoma multiforme (GBM) affects three out of 100,000 people, a rate that quadruples to 13 out 100,000 among people who are 65 and older. The average five-year survival rate from the time of diagnosis for GBM is only 3.3 percent, and is lower for people 65 and older.

Erlotinib increases survival in patients with advanced non-small cell lung cancer

An international clinical study led by Canadian researchers has demonstrated that a drug called erlotinib increases survival in patients with advanced non-small cell lung cancer who typically have no other treatment options.

Single mutation in a human sodium channel gene can trigger pain in people with primary erythromelalgia

Yale School of Medicine researchers report the first demonstration that a single mutation in a human sodium channel gene can trigger pain in people with an inherited pain syndrome known as primary erythromelalgia, according to a study published this month in the journal Brain.

Researchers gain better understanding of how nerves need to be reconnected after spinal cord injury

Nerve cells relay messages at blink-of-the-eye speeds by squirting chemicals called neurotransmitters across tiny gaps called synapses to awaiting message receptors. But lots of different receptors and neurotransmitters work simultaneously. Which goes where to send the proper message?

Congenital central hypoventilation syndrome (CCHS) offers clues to SIDS, sleep apnea

Imagine raising a child who stops breathing when falling asleep - and has to be reminded to visit the bathroom after drinking a Big Gulp. That's the dilemma faced by parents of children born with congenital central hypoventilation syndrome (CCHS).

Newly discovered gene mutation may account for many cases of immune deficiency

...in particular two syndromes known as immunoglobulin A (IgA) deficiency and Common Variable Immunodeficiency (CVID), report researchers in the July issue of Nature Genetics. The discovery may lead to a new diagnostic test for these conditions, which make people highly susceptible to infections and often go unrecognized because of a lack of good tests.

Bird flu could be carried out of Asia by migrating geese

Scientists are warning that migrating geese and other birds at a wildlife refuge in China, means the birds could carry the devastating virus out of Asia and spread the avian flu virus further afield.

Researchers discover sections of the chromosomes of lung cancer cells where cancer-related genes may lurk

With equipment designed to probe the smallest segments of the genetic code, researchers at Dana-Farber Cancer Institute and collaborating institutions have found something much larger: sections of the chromosomes of lung cancer cells where cancer-related genes may lurk.
